Supply and Demand?

supply and demand.. if the supply of one item doesnt meet the demand for the same item, people will actually pay more to get it. example when the anniversarry Corvette model comes out, the demand is so great that peolpe were actually paying up to $20.000 more to be able to get one. most of the time companies will increaser prices because the demand is high, wether they can meet the demand or not...The rest Im sure you can figure out yourself...
